1 00:00:09,900 --> 00:00:18,660 Hello, this is a podcast about ecosystems, but to start, the first thing we should know 2 00:00:18,660 --> 00:00:20,339 is what is an ecosystem? 3 00:00:21,399 --> 00:00:26,660 Well, if you don't know what is an ecosystem, I'm going to tell you now. 4 00:00:27,320 --> 00:00:35,820 An ecosystem is a community of living things and their environment, the world that surround 5 00:00:35,820 --> 00:00:44,259 those living things. Ecosystems can be very different ones from each other. Ones can be 6 00:00:44,259 --> 00:00:52,280 as big as an ocean and others can be as small as just a little pond. What we have to know 7 00:00:52,280 --> 00:00:59,000 about an ecosystem? In an ecosystem, as we have said before, there are going to be living 8 00:00:59,000 --> 00:01:05,719 things and also no living things. The living things are going to be called 9 00:01:05,719 --> 00:01:14,319 biotic factors and the no living things are going to be called abiotic factors. 10 00:01:14,319 --> 00:01:23,040 Biotic factors are usually divided into two groups, fauna and flora. Fauna are 11 00:01:23,040 --> 00:01:32,980 animals like dogs frogs crabs any other and flora are the plants that are in 12 00:01:32,980 --> 00:01:43,659 that place like trees buses grass etc the abiotic factors are the no living 13 00:01:43,659 --> 00:01:52,939 things that are in that area like for example rocks water or the sunlight one 14 00:01:52,939 --> 00:01:58,879 ecosystem is going to be different from another because of the place on earth 15 00:01:58,879 --> 00:02:05,239 where it is. Depending on the place the weather is going to be different, the 16 00:02:05,239 --> 00:02:11,419 light, the temperature, everything is going to be different so animals and 17 00:02:11,419 --> 00:02:17,620 plants are also going to be different depending on that temperature or rain. 18 00:02:17,620 --> 00:02:23,419 Now, we are going to see some examples of ecosystems. 19 00:02:23,419 --> 00:02:26,500 We have the grassland ecosystems. 20 00:02:26,500 --> 00:02:35,020 We can have a temperate grassland or the most known one, the savannah. 21 00:02:35,020 --> 00:02:39,740 Savannas are located in the tropical areas. 22 00:02:39,740 --> 00:02:46,740 This tropical area has two seasons, one in summer when it rains a lot and the other in 23 00:02:46,740 --> 00:02:54,500 winter when it doesn't rain even a little the lariat savannah is located in africa 24 00:02:56,580 --> 00:03:04,099 but the grasslands are not places where it rains a lot so there are not a lot of trees 25 00:03:04,099 --> 00:03:10,979 there are more grass and that's because they are called grasslands on the other hand 26 00:03:10,979 --> 00:03:18,780 And if we talk about rainy places, we can think that there can't really grow trees, 27 00:03:18,780 --> 00:03:23,860 so we can see the forest ecosystems. 28 00:03:23,860 --> 00:03:29,139 There are different forest ecosystems depending on their place on Earth. 29 00:03:29,139 --> 00:03:36,740 We can find Echiniferous forests, Edesidious forests, the tropical rainforest, or here 30 00:03:36,740 --> 00:03:40,800 in Spain, the Mediterranean forest. 31 00:03:40,800 --> 00:03:47,039 The most known and most beautiful ones are the tropical rainforests. 32 00:03:47,039 --> 00:03:53,419 These tropical rainforests are located in the equator and the temperatures are really 33 00:03:53,419 --> 00:03:57,759 high and it rains a lot. 34 00:03:57,759 --> 00:04:01,139 Another ecosystems are deserts. 35 00:04:01,139 --> 00:04:05,460 Deserts are the hottest and driest places on earth. 36 00:04:05,460 --> 00:04:14,280 During the day the temperatures are really, really high, but at night they drop to 0 degrees. 37 00:04:14,280 --> 00:04:21,720 The largest desert in the world is the Sahara desert that is in the north of Africa. 38 00:04:21,720 --> 00:04:28,939 All these ecosystems that we have seen till now are on land, but there are also ecosystems 39 00:04:28,939 --> 00:04:30,920 in water. 40 00:04:30,920 --> 00:04:37,300 We have marine ecosystems and freshwater ecosystems. 41 00:04:37,300 --> 00:04:45,000 Marine ecosystems are those that are in salt water, like for example coral reefs. 42 00:04:45,000 --> 00:04:49,800 Coral reefs are one of the most diverse ecosystems on Earth. 43 00:04:49,800 --> 00:04:55,540 They are home to about 25% of all marine life. 44 00:04:55,540 --> 00:05:02,399 There are also the shoreline, that is the place where the sea meets the land, where 45 00:05:02,399 --> 00:05:11,480 we can find also a lot of organisms like safis, mollusks and sea urchins. 46 00:05:11,480 --> 00:05:21,540 Freshwater ecosystems are those that are not in salt water, so we can't find them in lakes, 47 00:05:21,540 --> 00:05:25,480 rivers, streams and ponds. 48 00:05:25,480 --> 00:05:35,240 finished we are going to talk about a special ecosystem that is the urban ecosystem. It's the 49 00:05:35,240 --> 00:05:43,720 one that we know the most because it's where we actually live. The urban ecosystem has a lot of 50 00:05:43,720 --> 00:05:53,240 artificial elements that humans have made, but there are also some natural elements. Most of 51 00:05:53,240 --> 00:06:00,740 them are located in parks. Humans instead of adapting to ecosystems like other 52 00:06:00,740 --> 00:06:07,160 animals do, they have adapted the ecosystems to themselves. 53 00:06:07,160 --> 00:06:14,720 Summarize all this information I can said that ecosystems are those areas in 54 00:06:14,720 --> 00:06:21,079 the planet where different animals and plants lives and adapt to that place. 55 00:06:21,079 --> 00:06:28,740 hope you have learned more about ecosystems. See you soon!
